7800 Difficulty Switches in Atari 7800 Posted September 1, 2014 So glad to find this information. Left is (B)eginner and Right is (A)dvanced. There's got to be a good memory trick to remember that... OR I could just print out a label and stick it on my 7800. Maybe "When you get it right, you're (A)dvanced." would work as a memory thing. Why didn't they label them on the 7800?
